HII Region Temperature Structure

  1. Jun 5, 2007 #1
    I'm trying to use Osterbrock's book "Astrophysics of Gaseous Nebulae and Active Galacic Nuclei" to made a model of a pure Hydrogen HII region. I've got the ionization structure down, but I'm having trouble with the temperature. Can anyone recommend somewhere that shows what I should be getting?

    But the ionization doesn't have much to do with the temperature, since the hydrogen is being ionized by the photons over 13.6, not collisionally. Doesn't the temperature come from the excess energy (over 13.6) from the photons?

    The fact that all the sources mention that the temperature of the HII region is on the order of 104 K indicates that the electron (and perhaps ion) energy is about 1 eV. And I imagine there is some kind distribution of energy/temperature.
